摘要
目的对北京市密云县2014年食源性疾病监测中检出的9例都柏林型沙门氏菌病例进行流行病学调查,了解病例的流行病学特征。方法对9例病例资料进行整理,并采用电话访谈形式开展补充流行病学调查,了解病例活动史、发病就诊情况、分析患者感染来源。使用描述性流行病学方法进行分析。结果 9例都柏林型沙门氏菌病例以腹痛、腹泻等症状为主,男性2例;女性7例,最大年龄70岁,最小年龄17岁;县医院就诊3例,中医院就诊6例。职业:工人2例,学生、家民、干部及职员各1例,无业3例。居住:县城区6例,县城边村1例,乡镇2例。在电话调查过程中排除了病例间互相认识的可能性,没有共同接触史,感染来源于家庭外饮食的患者2例,来源于家庭内饮食的患者7例。在性别、年龄、职业、居住、暴露信息等方面均未发现明显关联。病例呈高度散发,病例之间尚无明显流行病学关联。结论通过本资料的分析,总结了病例特征,并对下一步监测工作提供依据,也为今后疑似同源性食源性疾病的流行病学溯源调查提供经验,同时对提高散发的同源性食源性疾病病例资料分析提供基础。
Objective To investigate the epidemiological characteristics of salmonella cases in Beijing in 2014, and to investigate the epidemiological characteristics of salmonella cases in Miyun. Methods Data of 9 cases were collected, and telephone interview were carried out to conduct supplementary epidemiological investigation including understanding the history of the case, the incidence of medical treatment, analysis of patients with infection sources.

No significant association was found in gender, age, occupation, residence and exposure. There was no obvious epidemiologic correlation among cases, Conclusion Through the analysis of the data, not only characteristics of patients were summed up to provide a basis for further monitoringand provides experience for epidemiological traceability survey, of future suspected homologous foodborne disease but also the ability could be improved to analyze sporadic cases of homologous foodborne diseases.
